SPECIFICATION forming part of Letters Patent No. 788,629, dated May 2, 1905 Application filed January 28,1904. Serial No. 190,935.

To all whom it may concern:

Be it known that I, MALooLM CAMPBELL, of Boston, inthe county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Fliers, of which the following is a specification.

This invention has relation to fliers, and has for its object to provide certain improvements on the flier shown in my Letters Patent No. 747,13 1, granted December 15, 1903.

Referring to the accompanying drawings, Figure 1 illustrates in perspective view a flier equipped with my improvements. Fig. 2 is a front elevation of the upper portion of the same. Fig. 3 is a perspective view of the upper portion of the flier and illustrates the yarn-retainer. Fig 4 represents a section on the line 4: 4. of Fig. 2.

On the drawings,-1O 11. respectively, indicate the'arms of the flier, the arm 11 carrying the yarn and the arm 10 being employed to counterbalance the weight of the arm 11 and its operative parts. The arm 11 is for a portion of its length concave-convex or substantially scmicylindrical in form, the concavity being on the inner face of the arm, so as to provide a deep groove or guide for the yarn. The grooved upper end of the arm 11 is provided with a substantially spiral groove 12, which extends from a point in the rear of the thread-eye 13 at the tubular top of the flier to a point substantially in line with the concaveconvex portion 11, so that the yarn 14 may be guided from the eye 13 to the groove or guide formed by the cavity on the inner face of the arm 11.

For the purpose of retaining the yarn 14 in the guide or groove 12 a yarn-retainer 15 is employed, consisting of a lug which projects or bridges across the groove, as shown in Fig. 4:, there being a narrow throat between the end of the lug and the top of the arm for the lateral passage of the yarn in threading the flier.

The lower end 16 of the arm 11 is round or cylindrical and has pivoted upon it the presserfinger 17 The presser-finger is connected to the tension-bar 18, the upper end of which is provided with a collar 19, encircling a cylindrical reduced portion of the arm 11 between the concave-convex portion thereof and the top portion of the arm. The arm 17 is provided with a laterally-projecting linger or guide 20, which is curved in the direction of its length, the curve being the arc of the circle struck from the center of the end 16 of the arm 11. The yarn 14 passes from the guide 12 into the concave face of the arm and thence past the guide 20 and is coiled one or more times about the arm 17 before it is passed through the eye 21 thereof.

A flier as above constructed may be either cast or drop-forged, is simple in construction, and highly eflicient in operation.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is 1. A flier having a yarn-carrying arm with a semitubular portion on its inner face and between its ends, a presser-linger pivoted to the lower end of the yarn-carrying arm and having a laterally-projecting guide, said parts being constructed as described,in consequence of which the yarn may be caused to lie in the concave face of said arm and pass therefrom past said guide.

2. A flier comprising an arm curved at its upper end and having its straight portion formed with a concave inner face, a spiral groove extending around the curved portion of the arm so as to conduct the yarn to the said concave face, and a yarn-retainer for maintaining the yarn in the said groove.

3. A flier comprising an arm curved at its upper end and having a straight portion against the inner face of which the yarn may lie, a spiral groove extending around said curved portion of the arm so as to conduct the yarn to the said inner face, and a yarn-retainer on the said curved portion of the arm for maintaining the yarn in the said groove.

In testimony whereof I have aflixed my signature in presence of two witnesses.
